Abstract—High-quality reconstruction of 3D geometry and texture plays a vital role in providing immersive perception of the real world.
Additionally, online computation enables the practical usage of 3D reconstruction for interaction. We present an RGBD-based
globally-consistent dense 3D reconstruction approach, where high-quality (i.e., the spatial resolution of the RGB image) texture
patches are mapped on high-resolution ( 1 cm) geometric models online. The whole pipeline uses merely the CPU computing of a
portable device. For real-time geometric reconstruction with online texturing, we propose to solve the texture optimization problem with
a simplified incremental MRF solver in the context of geometric reconstruction pipeline using sparse voxel sampling strategy. An
efficient reference-based color adjustment scheme is also proposed to achieve consistent texture patch colors under inconsistent
luminance situations. Quantitative and qualitative experiments demonstrate that our online scheme achieves a realistic visualization of
the environment with more abundant details, while taking fairly compact memory consumption and much lower computational
complexity than existing solutions.
